Application tiled December 15, 3887. Serial No. 257,977. (No model.)

To 6025 whom it many concern.-

Be it known that we, ISAAC B. KLEINERT and Bonner G. hL-iNvILLn, both citizens of the United States, the former residingin the city, county, and State of New York, and the latter at \Vatcrbury, in the county of New Ha ven and State of Connecticut, have invented certain new and useful Improvements in Ear- Muffs, of which the following is a specification, reference being had therein to the accompanying drawings.

Our improvement relates more particularly to that class of earmutfs in which the earloops are hinged to slides which are inclosed in a tube; and the invention consists in the peculiar construction and arrangement and combinations of parts, hereinafter described, and then definitely pointed out in the claims.

In the accompanying drawings, which illus trate what we consider the preferable form of our invention, Figure 1 represents a perspective view of our improvement in its open condition. Fig. 2 is a view of the tube and slides with parts represented as broken away. Fig. 3 is a view of thejoint between the slide and the ear-loop. Fig. lrepresents a slide of a diliercnt form detached.- Fig. 5 is a plan of the blank from which is formed the double washer of the hinge. Fig. 6 is a perspective view of the double washer detached, and Fig.

7 is a similar View of a cap serving the double purpose of a guide for the slide and to protect the end of the textile or other covering surrounding the tube.

All of these views except the first are on a much enlarged scale.

Referring now to the details ofthe drawings, A A represent ear-loops, of any convenient material, pivoted to slides B B, which are inclosed in a tube, (3, made in any convenientmanner and of any suitable material, but preferabl y of sheet-brass or from brass tubing flattened and bent to shape. The inner ends of these slides are bent, asshown at Z), so that when these ends come together, or nearly so, as shown in Fig. 2, they form stops and prevent the slides being drawn entirely out.

Surrounding the tube is a covering, D, of some textile material, preferably of braided mohair, and at the opposite ends of the tube are caps E E, each havinga hole, 0, in its extreme end, through which one of the slides passes. This cap is passed over the outside of the covering D and holds it in place on the tube, thus performing the double function of protecting the end of the textile covering and forming a guide for the slide. 'lhcjoint be tween the slides and ear-1oops is made by fornr ing the end of each into a loop and inelosing the same in a double washer, F, through which is passed a rivet, G. These double washers are formed from blanks of the shape shown in Fig. 5, having a neck, jiaud stops /j",so that when bent into shape the blank will become a double washer connected together at f, and having stopsff projecting in opposite directions, as shown in Fig. 4.

In lieu of slides made of round wire wesometimes use flatwire for this purpose, in which case it will be found preferable to make them of wire of the width of the inner longest diameter of the tube and set their flatsides together so as to lap each other. Their ends may be bent to form stops, or any other suitable means may be used to prevent their coming out of 7 the tube accidentally.

It will be seen that by the construction shown an ear-muff frame is produced that is not only cheaply made, but is durable and will fold into small space.

By the use of the double washers the parts of the hinge are firmly secured together, and the stopsff on the washers serve to limit the movement of the ear-loops and keep them in their proper place, for the stopf willcome 8 in contact with the slide, while the pivoted part of the ear-loop will come in contact with the stop f.

In some cases we may make the neck f in the position shown in dotted lines in Fig.6, in 0 which case it will serve the purpose of one of the stops.

The caps E may be secured in any convenient manner. \Ve have found it to be a cheap yet good way to drive a punch into the 5 body of the cap, and thus force a portion of the metal of the cap into a depression in the tube, and both cap and tube are in this manner securely fastened together. After the parts are put together, and to prevent one of the :00

slides being drawn out farther than the other, we usually make a deep depression in thetube O, as shown at a in Fig. 1, which will prevent either slide from moving more than half its 5 length out of the tube. This, though important, is not absolutely necessary.

What we claim as new is- 1. The combination, with the slide and-earloop of an ear-muff, of a double washer hav- 10 ing its opposite portions connected by a neck at one side of the same and embracing and securing together both slide and loop, and a pivot passing through the double washer, the slide, and loop, substantially as described.

1 2. The combination, with the slide and loop of an ear-muff, of a double washer provided with stops to hold the loop in its proper position and the pivot passing through the double washer, the slide, and loop, substantially 20 as described.
